Abstract
A system and method of combating, controlling and extinguishing fires (60) in flammable liquids (65) stored in atmospheric tanks (50), which may comprise low-viscosity materials, the combat being performed by injecting streams of a gaseous extinguishing fluid (16) at ambient conditions, at the bottom of an atmospheric tank (50) through an injector assembly (14), not enabling the formation of residues after the combat of the fire and enabling the fluid (65) to be used normally after the fire has been extinguished. The system does not use water and does not expose people to risks while combating the flames, while minimizing the emission of toxic smoke into the environment and to neighboring populations due to the speed of the combat.
Claims21
A system (1) to combat fires (60) in flammable liquids (65) in atmospheric tanks (50) comprising an extinguishing fluid source (10), a recondensation unit (11), a vaporization unit (12), a fluid transfer line (13) and an injector assembly (14) fluidly connected to each other, wherein the extinguishing fluid source (10) is arranged to supply an extinguishing fluid (16) to the system (1), the extinguishing fluid (16) being propelled and conducted along the fluid transfer line (13) until it reaches the injector assembly (14), the injector assembly (14) being positioned inside the atmospheric tank (50) and arranged so that the extinguishing fluid (16) is discharged inside the atmospheric tank (50) such that said extinguishing fluid (16) in liquid phase is immediately sublimated in gaseous phase in the midst of the flammable fluid (65) inside the tank (50) and emerges in the tank (50) when inserted in the tank (50).
A method of combating fires (60) in flammable liquids (65) in atmospheric tanks (50), using an extinguishing fluid source (10), a recondensation unit (11), a vaporization unit (12), a fluid transfer line (13), and an injector assembly (14) fluidly connected to each other, said method comprising the steps of:
- storing an extinguishing fluid (16) in the extinguishing fluid source (10);
- extracting the extinguishing fluid (16) from the extinguishing fluid source (16);
- conducting the extinguishing fluid (16) along the fluid transfer line (13);
- discharging the extinguishing fluid (16) into the atmospheric tank (50).
